Hi all, I'm new to this forum, so I apologize in advance if I posted in the wrong section. I have an engine out of an 88 mustang and am trying to identify which fuel line is the feed and which is the return. Here is a picture of the lines that run from the gas tank. The line with the yellow arrow pointing to it also has a valve attached to it (I've attached a picture of the valve, I think it's called a schrader valve). From what I have read, it seems the schrader valve is attached to the feed line. If anybody can confirm which is which, I'd greatly appreciate it.
